MERCEDES A160 RATTLING

2003 Mercedes Benz 190d • 2WD Manual • 53,000 miles

My Mercedes A160 2003 is very noisy on tick over, like a rattling, ticking. Once you pull off or rev the engine the noise reduces. Its just had a service but I've heard this rattling is common on this diesel. What can I do to stop the noise? Also is it causing damage to the engine? Thanks
